SICK

$249.95

SICK GTB2S-P5451 G2 photoelectric proximity sensor with background suppression, 2-120 mm range, 640 nm red light, 800 Hz switching frequency, IP67 rated, includes 10 m M8 3-pole cable.

Compact Photoelectric Proximity Sensor for Precise Detection:

The SICK GTB2S-P5451 G2 photoelectric proximity sensor is an industrial photoelectric sensor engineered for accurate short-range detection in automated manufacturing and packaging environments.

  • Scanning range: 2 to 120 mm
  • Switching frequency: 800 Hz
  • Sensor size: 7.7 x 27.5 x 13.5 mm
  • Weight: 18 g

Key Features and Advantages:

SICK's G2 series, including the GTB2S-P5451, utilizes background suppression technology for reliable object detection, even in challenging environments with reflective or varied backgrounds. This makes it more accurate than standard photoelectric proximity switches, reducing false positives and improving performance near conveyor belts or mounting fixtures. The visible 640 nm red light simplifies setup and alignment, while the compact design fits easily into tight spaces.

Robust Construction for Industrial Applications:

The GTB2S-P5451 photoelectric proximity sensor features a durable IP67 housing and a 10 m M8 3-pole cable for flexible installation options. The high switching speed supports fast-moving production lines where rapid detection is critical.

When to Choose SICK GTB2S-P5451:

Select the SICK GTB2S-P5451 G2 photoelectric proximity sensor for machine vision, automated sorting, object presence detection, or packaging lines where compact size, precision, and immunity to background noise are required. Background suppression makes this model especially valuable in comparison to non-suppressed photoelectric sensors.

The SICK GTB2S-P5451 G2 detects objects from 2 to 120 mm away. Background suppression technology eliminates false triggers from reflective surfaces or varied backgrounds.
Yes, the GTB2S-P5451 switches at 800 Hz, making it fast enough for rapid detection on high-speed conveyor belts and packaging equipment.
The sensor has an IP67 sealed housing that withstands factory floors, spray, and washdown areas.
The visible 640 nm red light beam simplifies alignment and setup without requiring external tools or lasers.
The compact 7.7 x 27.5 x 13.5 mm body and 18 g weight allow installation in confined areas where larger sensors cannot fit.
The sensor includes a 10 m M8 3-pole cable that enables flexible installation configurations for different mounting layouts.

Photoelectric sensor with background suppression versus standard proximity switches:

The SICK GTB2S-P5451 G2 is a compact photoelectric sensor designed for short-range detection where false triggers from reflective surfaces or mounting fixtures are a concern. Choose this over basic proximity switches or non-suppressed photoelectric sensors when accuracy near conveyor systems or variable backgrounds matters.

  • For tight mounting spaces under 8 mm width, the 7.7 x 27.5 x 13.5 mm body fits where larger sensors cannot.
  • For production lines running above 500 parts per minute, the 800 Hz switching frequency captures objects without delay.
  • For detection near shiny metal fixtures or reflective conveyor belts, background suppression eliminates false positives that trigger standard photoelectric sensors.
  • For washdown or outdoor assembly areas, IP67 sealing and the 10 m M8 cable support wet and dusty factory floors.
  • For quick setup and alignment, the visible 640 nm red light beam reduces trial-and-error installation on crowded production cells.
